To all whom itmay comm; 1 g

Be it known that I, JOSEPH rBRAUNINGER, a citizen of the Unite'd States, residing' at Trenton, in the county ofMercer and State of New Jersey, have invented acertainnew and useful Gas-Stove, of-which the following is a specification.

This invention relates to gas stovesand "has special reference .to a combined gas stove and water heater forming improvement over my prior applicationfor patent on combined gas stoves and 'waterheaters, filed March 9, 19M, and bearing the SerialNumber 823,484.

-i-I have found,- in using the stove of my 'priorjapplication,that the lateral gas sup- :ply pipes could be dispensed with by modifying the structure in certain ways,and this without a'ifecting its efiiciencyas either a stove or water heater.

One object of the invention, therefore, is

to produce a modifiedand improved stove of the general type previously disclosed in my prior application and which will enable the lateral gassupply pipesto be dispensed with without in any way afiecting the .efficiency of the device. I

I have 'also found, m practice, that it is advisable, both for improving the 'manner I burner or mixing tube 21 the body portion "of whlch 1s oblately ovate in cross section of heating the water-and for-increasing the life. of the device, that the lateral flame pasprove the burner structure in a device of i this character. I a

With the above and other objects in view as will be hereinafter apparent the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 isa plan view of the improved stove. Fig. 2 is a section on the line 2-42 of Fig. 1. Fig. '3 is an enlarged detail section on, the line 3--3 of Fig. 1. Fig. 1 is a detail plan view partly section with the hood removed. Fig. 5 is an end View of the device showing a modiof the main water heating chamber. pending from the outer edges of the flange Specification of LettersPatent. t te j 1915. p I Application filed sea. 5, 1915.

'detail end view of the burner tube.

In carrying out the above, mentioned ob jects there is providedan inner casing which contains the combustion chamber 10 and the wager heating chamber indicated in general at This waterheating chamber consists of a main body portion 12 surrounding the ]combustion chamber of substantially inverted U-shape and a peripheral or flange portion 13 extending laterally from the upper part portion are skirt walls 14. Extending later- ;allythrough the'legs of the main body portion is a plurality of tubular flame passages .15 and through the flange portion extend similar flame passages-16 extending vertically through such flange portion.

In the main water heating chamber there IS a water inlet opening 17, an outlet opening 18and a cleanout opening-19. Furthermore there is a centralvertical opening 20 extending through thebight of the Ushaped body portion of the water heating chamber. It will thus be evident that all of the flame passages are water jacketed. I

Extending through 'hechamber 10 is a and which is provided with lateral openings pose'of better mixing the air and gas and of producing a more even and uniform flow.

In both the forms shown in Figs. 1 and 2 and the form shown in Fig. 5there is provided a hood 27 but in the first form, which is designed to use the device as a stove as well as a water heater, a spreader cone 28 is provided above the opening 20 and this spreader cone is surrounded by openings 29 for the escapeof the heated air and prodnets of combustion from the openings 20. p In each case the hood isheld spaced from the heater by suitable means such as is shown at 30. i

The device, when in use, heats the water in the water chamber in a highly eflicient manner owing to the fact that the flame l Xformed substantially central thereof and being provided with skirt walls depending 3O 1 from theouter edges of the horizontal @portherein and provided with lateral flange portions extending from and communicat ing with its upper part, said casing having a horizontally extending tubular opening from the outer edges of the horizontal portions of the Waterchamber to form lateral pockets at the sides of the tubular opening,

, there being walled openings through the sides of the water chamber affording coinmunication between the central opening and the pockets and the horizontal portions of the water chamberover the pockets being provided with vertically disposed walled openings.
